HIGH: Choose the value of the high switching threshold of the output.
INVERT: Invert the output or not.
DELAY: Choose the value of the time-out before switching for each digital output. This is valid for both output
thresholds. Switching is only done if one of the thresholds, high or low (functions "High" or "Low"), is exceeded
for a duration longer than this time-out.
configuring in "Window" operating

The output status changes as soon as any threshold (low or high) is reached..

PV: Choose the process input associated with the output selected.
LOW: Choose the value of the process input for the low switching threshold of the output.
HIGH: Choose the value of the process input for the high switching threshold of the output.
INVERT: Invert the output or not.
DELAY: Choose the value of the time-out before switching for each output. This is valid for both output
thresholds. Switching is only done if one of the thresholds, high or low (functions "High" or "Low"), is exceeded

"FastPWM" operating

PV: Choose the process input associated with the output selected.
LOW: Choose the value of the process input ("PV") corresponding to 0% PWM.
HIGH: Choose the value of the process input ("PV") corresponding to 100 % PWM.
INVERT: Invert the output or not.
FREQUENCY: Choose the value of the output frequency (= 1/T2), from 2 to 2000 Hz.
